Server/friend favorites

I know there have been people who have suggested this but with no details, I would not only suggest being able to favorite friends, but also be able to do it for servers, which would prioritize notifications for them and show them at the top of lists, for servers there would be an option in server settings or something, and for friends when you add them it gives you a screen a bit like Xbox does and lets you change it later, as for servers, thanks for reading and have a great day!
